[question] How to list all classes that used in a file?

[erlangparasu]

For example:

class MyKlass {
    public function createBook()
    {
        $book = new Book();

        return $book;
    }

    public function formatter()
    {
        $formatter = Utils::getFormatter();

        return $formatter;
    }
}

How to print list of class usage of that file?
In this example expected output will be: "Book" and "Utils" class.
Thanks

Currently i found:
Stmt_Class, Expr_StaticCall, Name_FullyQualified and Expr_New
to able to find class usage.

Any other possible keyword to check? Thanks

There's a lot of them - there's also AST_USE/AST_GROUP_USE which would tell you what use Xyz\Foo; meant Foo was.

You may want to use a static analyzer instead, e.g. https://github.com/phan/phan

For example, https://github.com/phan/phan/blob/5.2.1/tool/pdep#L20-L54 would print the full dependency graph of classes
